Combined the 2011 MVP2 Award winners cut greenhouse gas emissions by 800,000 tons, reduced air pollution by nearly 100,000 tons/year, conserved more than 6 billion kilowatts of energy, and reduced water consumption by over 45 million gallons/year while cutting costs by over $10 million.
P2 Project/Program Award: Cintas, Inc. (Everett, Puyallup and Yakima, WA)
Cintas-Washington State implemented a program to eliminate 25,000 gallons of detergent that contained nonylphenol ethoxylates (NPEs) in the laundry process. In addition to using safer chemicals and inspiring others to do likewise, Cintas-Washington State facilities saved over 19 million gallons of water by developing all high efficiency washing formulas which strategically eliminate certain washing and rinsing steps, resulting in a 33% water use reduction or 240,000 gallons of water and saving $171,000 per year. The three facilities involved in this project also implemented energy conservation measures which together resulted in $60,000 in savings.
P2 Project/Program Award: IBM Vermont (Essex Junction, VT)
The IBM Vermont Facilities, Manufacturing, Environmental and Chemical Lab team members worked collaboratively on the design, development, and installation of a new U Tube scrubber air abatement technology. The scrubber is more reliable, cost effective, and energy efficient and results in better emissions control compared to what is commercially available today.
IBM Vermont's previous point of use scrubbers used filter media and recirculating pumps to provide the contact area to absorb inorganic chemistries. These scrubbers plugged frequently due to particulates in the air stream, resulting in excessive tool down time and maintenance costs. There was additional negative impact to product yields. Another problem was that the point of use scrubbers utilized a heating unit that proved to be ineffective and wasted energy. The U Tube design changes the standard approach by using water and air flow in the same direction to remove the majority of air contaminants in the first stage. The second stage (or polishing step) uses a more conventional countercurrent flow to remove even more of the remaining chemicals from the air stream prior to sending it to the central scrubber, which does the final scrubbing prior to discharge. Since this improved design is so effective in removing chlorine and hydrogen chloride gases, no additional treatment chemicals (such as caustics) are needed to adjust the pH. Furthermore, not having to introduce treatment chemicals allows the U Tube scrubber to be much more energy efficient because no pumps, actuators, and other electrically driven parts are required.
This design has resulted in significant reduction in Chlorine and Hydrogen Chloride (HCl) emissions from our semiconductor manufacturing operations. It has also reduced annual energy use by 1,110,518 kWh and has potential water savings of over 7 million gals over the conventional air abatement previously installed. The energy savings from this project equates to approximately 35 metric tons of carbon dioxide reductions annually. Total cost savings from this project are $220,000/year in energy, maintenance, and spare parts costs.
P2 Project/Program Award: IBM Vermont (Essex Junction, VT)
IBM Vermont used Lean Manufacturing and Green Sigma techniques to identify a less than optimized nitrate removal process in their facility's wastewater treatment plant. With the help of Statistical Process Control to help manage the large amounts of wastewater data and jar tests, IBM Vermont added an anoxic (no oxygen) cycle to their treatment process with an organic waste spike (using the current sanitary influent) between the two aerobic cycles of the Sanitary Sequential Batch Reactor (SBR) treatment process. This change was fully implemented at the end of November 2009 and reduced the nitrate output by between 49% and 60% annually in the biological effluent, and subsequently by between 9% and 28% in the final industrial effluent from 2007 to 2010. Annual energy savings from this process change amount to 77,000 kilowatt hrs due to decreased blower use.
IBM Vermont’s data management systems were an integral tool in making the above project possible. The data management systems allowed the IBM team to review, analyze and optimize the nitrates removal process in their wastewater treatment systems while ensuring that other process parameters were not adversely impacted. By implementing improved process cycles and an organic food spike, IBM demonstrated that significant improvements in water quality can be made without significant capital investment.
P2 Project/Program Award: IBM East Fishkill (East Fishkill, NY)
In 2003, IBM East Fishkill (EFK) initiated a Pollution Prevention (P2) Program investigation of alternative technologies to sodium bisulfite addition for reduction of hydrogen peroxide (“peroxide”) in its site waste streams. In early 2009, a catalytic enzyme process was qualified to replace the existing sodium bisulfate reduction process to remove peroxide from the wastewater. The new process uses a small quantity of enzyme to catalyze the decomposition of peroxide into water and oxygen without contributing TDS to the site final effluent discharge and at a fraction of the cost. The design of the new process incorporated existing building equipment as much as possible and was seamlessly integrated into the existing treatment system. Design and construction of the full scale peroxide treatment system was started and completed in 2009 with startup continuing through March 2010. This new treatment process eliminates use of 38% sodium bisulfate (510,000 gallons/year) and the subsequent 50% sodium hydroxide (135,000gallons/year) for acid neutralization, and reduced chemical costs by $675,000 annually while also reducing energy use and 270 tons/yr of greenhouse gas emissions.

P2 Project/Program Award: SABIC Innovative Plastics (Mount Vernon, IN)
The SABIC Mt. Vernon, Indiana engineering thermoplastic manufacturing site has converted its approximately 2.5 million gallon/year sodium nitrite-containing non-hazardous wastewater stream to a product, generating $100,000 in net revenue annually. In 2008, SABIC, together with Calgon Carbon Corporation, successfully piloted a purification process at Chem Group in Evansville, Indiana to remove the organic contaminants from the waste stream through carbon treatment. After an extensive internal environmental, health and safety review, SABIC began converting and selling 30% of the sodium nitrite wastewater stream. In March 2011, a SABIC-designed $2.5 million dollar system to harvest all the sodium nitrite from the operation was completed. The new system produces in excess of 6 million pounds per year (dry weight) sodium nitrite for their customers, and eliminates waste and the need to incinerate that waste. All the former waste material is carbon-purified at a zero-water discharge site in Evansville, Indiana near the SABIC facility. The amount of sodium nitrite recovered and sold is approximately 10% of the United States annual sodium nitrite consumption.
